QUESTION 12

QUESTION 11

A magnet of mass 7.98 kg is suspended from the ceiling by a cord as shown. A large magnet is somewhere off to the right, pulling on the small hanging magnet with a constant force of F = 151.6 N. At what angle theta ?with respect to the vertical does the magnet hang?

QUESTION 12

Consider the same situation as in the previous problem. This time the magnet has mass 7.51 kg and the force pulling the magnet to the right has magnitude 150.9 N. What is the magnitude of the tension force in the cord?

QUESTION 13

Same situation as in the previous two problems this time the magnet s mass is 5.29 kg and the magnetic force pulling it to the right is 67.0 N. The length of the cord is 1.06 m, and the ceiling is 3.16 m above the floor. Suppose that you cut the cord and the magnet falls to the floor while still being pulled to the right by the force of 67.0 N. How long will it take the magnet to hit the floor?

QUESTION 14

Same situation as in the previous problem this time the magnet has mass 6.98 kg, the force pulling it to the right is 118.6 N, the cord has length 1.21 m and the ceiling is 3.06 m above the floor. How far to the right of its start point will the magnet have traveled when it hits the floor after the cord is cut?

QUESTION 15

OK, one more time. This time the magnet has mass 3.08 kg and the force pulling it to the right is 78.9 N. When the magnet hits the floor, it continues being pulled to the right by the same magnetic force as before. The coefficient of kinetic friction between the magnet and the floor is 0.572. What will the magnet s acceleration be as it slides to the right along the floor? (Assume static friction is overcome and the magnet will slide.)
